Zaha could be joining Marco Reus, Mario Gotze and Jadon Sancho at Dortmund

Dortmund will face competition from Tottenham and Everton, though, who are both thought to be keen on the pacey winger.

Zaha was named Crystal Palace Player of the Year for the third year in a row at the end of last season and would be difficult to replace in South London.

This is despite the fact that Palace are expected to shatter their record transfer sale, which currently stands at £25m following Yannick Bolasie's move to Everton in 2016.

Roy Hodgson will need to make signings soon with Yohan Cabaye and Bakary Sako already leaving the club this summer as the Eagles will be desperate to avoid a repeat of last season's Premier League start.
